Endpoint Vulnerability

RSA Signature Forgery in NSS

Description

Antoine Delignat-Lavaud, security researcher at Inria Paris in team Prosecco, reported an issue in Network Security Services (NSS) libraries affecting all versions. He discovered that NSS is vulnerable to a variant of a signature forgery attack previously published by Daniel Bleichenbacher. This is due to lenient parsing of ASN.1 values involved in a signature and could lead to the forging of RSA certificates.
